Boil the potatoes in salad water, until tender. Peel and mash them with a potato masher, then add the milk and the flour.
Peel the apple and cut into thin slices.
Fry the minced onion in a pan with butter until tender, then add the apple slices. Cook 10 minutes, until creamy. Add the marjoram leaves and remove from heat.
Divide the potato puree into eight parts. Using your hands, shape them into circular patties and place them on a floured surface.
Put half speck slice on each patty, and put the apple mixture on them.
Close the croquettes, using flour when needed.
Fry in hot oil, turning frequently until golden brown.
Serve hot.
